Born in Mitaka, Tokyo to a Japanese mother and a German American father,[1] Wentz became involved in the entertainment industry at a very young age.
Wentz initially started as a model at the age of four and made his acting debut as the role of Chip in the Four Seasons Musical Troupe production of Beauty and the Beast.
He became famous as a child actor as a regular on the NHK television show, Tensai Terebi-kun (天才テレビくん), where he played bass guitar and piano at the age of ten.
[3][user-generated source] After Tensai Terebi-kun ended, Wentz continued to play music and started the band WaT with Teppei Koike.
His popularity may be derived from his self-mocking "comedian" character, as he often talks about his "foolishness", short height, and difficulty in speaking English.
